purpose of operating on clothing beingwashed at difl'erent stages of their treatment.

WVith the above and other objects in view, the invention consists in the novel construction and arrangement of parts hereinafter described, shown in the drawings and claimed, it being understood that changes falling within the scope of what is claimed are contemplated.

In the drawing Figure 1 is a view of the machine looking at the operators side; Fig. 2 is a view of the opposite or driving side; Fig. 3 is a top view; Fig. 4 is a front elevation of the machine; and Fig. 5 is a vertical cross section taken centrally of the washing machine.

The frame of this machine is of a longitudinal form and comprises the corner posts 1 which are connected longitudinally by means of the sill 2 at the front and the sill 3 at the rear of the machine. Transversely the frame is connected by the cross sills 4:. At the top of the frame, and extending lengthwise thereof, are side strips 5 which are connected at each end by means of cross pieces 6. Mounted on the frame at one end thereof, is a washing machine 7 which may be of any suitable construction, and has the lid 8 which is hinged as at 9 to be. swung away from the top of the machine. Any suitable mechanism is employed for operating the agitator or stirring device 10, and is mounted, as usual, on the top of the machine, the mechanism shown consisting of the yoke 11, which is mounted on the top of the machine for sliding movement and a flexible cable or chain 12, which is connected to the ends of the yoke and wound about the spindle 13 at the top of the shaft 14 of the agitator 10 so that as the yoke 11 slides it causes the spindle 13 and the agitator 10 to turn. A shaft 15 is journaled on the top 8 of the machine and at its inner'end, adjacent the yoke 11, is provided with a disk 16, wh ch has an eccentrically disposed pin 17 which engages a vertical slot 18 in an upstandlng portion 19 of the yoke 11. As 1s apparent, the rotation of the shaft 15 will cause the pin 17 to operate in the slot 18 and impart a reciprocal movement to the yoke 11, whereby the agitator 10 will be caused to oscillate.

Extending lengthwise of the frame of the machine, at-the rear thereof, and near the top, is an endless sprocket chain 20 which is driven by a sprocket wheel 21 on the main or drive shaft 22 at the machine end of the frame. This shaft 22 is provided with a pulley 23 or other means whereby the shaft may be power driven. The chain 20 travels over a chain-guide throughout its entire length, which chain-guide is constructed -with a stationary part 24 adjacent the machine and a part 25 which is pivotally connected with the stationary part 24: and vertically movable to engage the chain with, anddisengage it from parts hereinafter described. The chain guide is provided at the end distant from the drive shaft 22 with an idler 26 which is connected with chain tightening means 27 whereby the chain may be held at the proper tension. At this outer swinging end of the chain guide there is also provided a bracket 28 mounted on the frame, to confine the chain guide in its movement. The drive shaft 15 of the washing machine is provided with a sprocket 29 which engages the chain 20 when the cover 8 of the machine is lowered to the operating position, and said sprocket is moved out of engagement therewith, when the cover of the machine is raised.

Mounted upon the frame of the machine are two receptacles 30 and 31, the receptacle 30 being located next to the machine 7 and the receptacle 31 being located next to the receptacle 30, it being the intention that the clothes, after being washed in the machine 7, shall be transferred to the rinse water in the receptacle 30 and from the receptacle 30 to the bluing water in the receptacle 31.

Vays are provided at each side of the receptacles 30 and 31 and at the top thereof for a frame 32 which is adapted to slide lengthwise of the frame to a position adjacent the machine 7, and to various positions above the receptacles 30 and 31. This frame 32 supports a wringer 33 of any suitable construction, which has a shaft 34 extending to the rear side of the frame and this shaft is provided with a sprocket 35 positioned above the chain 20 and adapted to be engag'ed by said chain when the carrier 25 is raised.

Pivotally mounted to the rear sill 3 of the frame, are levers 36 which extend to the front or operator side of the frame and are provided with pedals 37 conveniently 10- cated for operation of the wringer in its different operating positions. These levers have a flexible connection 38 with a bell crank 39 which is pivoted to the frame of the machine under the carrier 25, and this lever 39 has an arm 40 extending laterally therefrom and provided with a part which engages the under side of the carrier 25. The connection of both the levers 36 with the bell crank lever 39 is such that pressure on either of the pedals 37 will raise the carrier 25, and the weight of the carrier 25 on the arm 40, automatically returns the pedals to their original position.

Assuming that the shaft 22 is being driven, the chain 20 will be constantly driven, and said chain is normally in.engagement with the sprocket 29 of the machine, and normally out of engagement with the sprocket 35. When the washing machine is to be rendered inoperative the top 8 thereof is swung upwardly on its hinges 9, which movementdisengages the sprocket 29 from the chain 20 and discontinues the operation of the machine.

When the wringer is to be used it is shifted lengthwise of the frame to the desired position and pressure applied to either ofthe pedals 37which pressure through the flexible connections 38, bell crank 39 and arm 40 thereof, elevates the chain carrier 25 and brings the chain 20 into operative engagement with the sprocket 35 of the wringer. The wringer continues in operation while pressure is applied to either of the pedals 37 and when the pressure is removed, the carrier 25 and chain are returned automatically to the lowered position out of engagement with the sprocket 35.

What I claim is:

1. In a mechanism of the class described, the combination of a support, a shaft journaled for rotation in said support, a supplemental support slidable bodily upon the main support for movement in a single fixed plane longitudinally of the main sup port, operating mechanism upon the supplemental support, a guideway at one side and extending the length of the main support, an idler element at the outer end of the guideway, a driven element carried in the guideway, and connected to be driven from the drive shaft at one end and supported upon the idler element at the outer end of the guideway, and means for adjusting the guideway support for the driven element whereby the latter may be caused to engage and operate the operating mechanism on the supplemental support in any of the positions of adjustment.

2. In a mechanism of the class described, the combination of a suitable support, a frame carried by said supportand adapted to slide bodily thereon, in a single fixed plane longitudinally of the support, bearings in said frame, a pair of horizontally disposed roller shafts, geared together and mounted in the bearings of said frame, an engageable element on one of said shafts, a power shaft mounted in the support, a guideway extending lengthwise of the support of the frame and comprising twosections, one fixed and the other swingable withrelation to the fixed section, an idler ele- V ment at the outer end of the swinging section of the guideway, a continuously driven element connected, to be driven from the power shaft, the same being carried within and extending the length of the guideway, its outer end being supported upon thelidler element at the outer end of said guideway, and means for swinging the movable section of the guideway to cause the drivenelement to be engaged with or disengaged,

at will, from the engageable element on one of said roller shafts in any of the positions of adjustment of the slidable frame.

3. In a mechanism of the class described, the combination of a support, guideways on said support, a slidable frame upon said support connected with the guideways thereon in a relation that the former may be moved to different positions on said support, a drive shaft, operating mechanism upon the frame provided with an engageable element adapted to be engaged by a driven member, a guideway upon the supportextending lengthwise thereof,and in the line of movement of the frame, the same being pivoted at one end to permit it to swing, a supporting element adjacent the free end of the guideway for supporting the driven member, an endless driven member carried in the guideway, and connected to be driven wise of said support and pivoted thereto at the end adjacent said drive shaft, a support for a driven element at the outer or free end i of said guideway, an endlessdriven element disposed in the guideway and connected with the drive shaft to be driven therefrom, and with the supporting element at the outer end of said guideway, a frame mounted upon the support intermediate the drive shaft and the outer end of the guideway adapted to be moved upon the support lengthwise of the guideway to different positions of placement intermediate said drive shaft and the outer end of the guideway, an operating mechanism upon the frame provided with an engageable member, and-means for swinging the guideway into positions to cause engagement 0r disengagement of the endless driven element with the engageable member on the operating mechanism in any of the positions of placement of said frame.
